Camera causing BSOD - 5672 WLMi

I have an Acer Aspire 5672WLMi laptop and it has a built-in OrbiCam, every once in a while I hear a sound as if I was plugging/unplugging an USB device, sometimes it does that twice and then stops but there's times, like a few mins ago, that it goes crazy and I get a Blue Screen.
The message I get is "File lv321.sys has caused an error. Page fault in non paged area" and makes me restart.
After I do that, Microsoft Error Reporting tells me that I should update the drivers although I already did that or to unplug the camera, which is impossible since it's built in.

I have searched on Google but couldn't find much information except perhaps the wires that connect the camera might be loose/damaged and that's what causing it.

I have disabled it on the Device manager but it won't solve anything.
Is there a way to completely disable the camera port?
What can I do to fix it?

The laptop is almost 2 years old and is not under warranty.

 

I had the same problem / having the same problem with mine. The connection is starting to go, not much I can do.

I disabled my camera under device manager and I have been fine. The wire from the camera runs though the main video cable bundle going down the left side hinge on the lcd screen.

Yea nothing you can do on a larger scale unfortunately.

Another possible fix is to download the latest drivers from Logitech's site. This fixed my problem to start.

 

Alright thanks, figured as much guess I'll have to get it repaired.

Another problem I'm having with it is that it runs too hot, 70C while just browsing/using word and about 85-90 when gaming.
The fan is on low speed until it hits the 80s, will upgrading the BIOS fix this?
The one I have is 1.3230, downloaded 1.3239 from the acer page but haven't installed it yet, is there any risk installing it with WinPhlash? I'm a noob so I don't want to cause it any damage.

 

yep had the same problem.pain in the backside.

flashing the BIOS is easy with winphlash.but before you start download the update then read the readme and check that it has a fix for the slow fan.
if not then get yourself a cooling pad.they are cheap and work well also check that dust is not blocking the inlet for the fan.
hoover and a good brush will help cleaning this away.
good luck

The heat issue I ran into was due to the fan failing. The odd thing is that it spun freely and didn't rattle like a bad ball bearing. I replaced the cooling module and it solved all my heat and stability issues (I was having to down clock to just stay afloat).

I now have a verticle line in my screen... so there is a connection issue somewhere that needs to be resolved.

I may end up doing a dismantle guide to determine the issues with the screen and camera. I'm assuming the issue is due to opening and closing the screen so much

I have used this laptop every day for the last 3 year so it's to be expected (I've defiantly got my moneys worth out of it and used it far more than the standard user).

SSX, the verticle line is the connection at the back of the screen.
try this,gently push against the lid at the back about a quarter to a third of the way down going from left to right.
turn your screen background color to black, as this will show the line/s better.

my 7110 had this problem after my 18month old nephew stood on it.
the fix i found by accident..i used a clear sealer to stop the connection moving again....still working fine.

 

Yea I had the LCD unit out and flipped over. I'm going to need to either disconnect the camera from the monitor at the base of the motherboard or keep it disabled in device manager.

I'll get pictures of the full breakdown in the days to come as well as my outcome.

 

Alright, when in doubt tear it apart right? Well I took the time and I have a full step by step for fixing the camera issue(s).

Camera Issues on the 5670 series

The connection between the camera and the motherboard can be disconnected or lose. You have two options in the case.

Option 1. Disconnect the camera from the motherboard

This requires taking the screen out completely and replacing the module. This should not be done unless you are trained in notebook replacement and repair, and even then I would question the standard "tech" being able to replace the unit without breaking something else!

To disconnect the camera from the laptop motherboard you will need the following equipment.

Phillips head screwdriver (small)
Flat head screwdriver (small)
Needle nose pliers

Step 1 - Disconnect the battery and AC Power, and remove the 3 screws from the back of the laptop

Step 2 - Open the laptop and set the screen flat so it is fully horizontal.

Step 3 - Gently pull up on the two plastic risers that cover up the hinges, and remove the entire plastic cover.

**NOTE** BE CAREFUL AND DO THIS VERY GENTLY! The edges of the cover are "hooked" into the lower 1/2 of the unit. You can see this by going here - http://forum.notebookreview.com/showpost.php?p=1790534&postcount=3

You will see the pictures below show the lcd screen removed from the 5670 series laptop. That cable in the middle is your camera cable.




Step 4 - Take a needle nose pliers and disconnect the cable shown below. My cable was in there VERY securely and I spent 2 min's or so gently wiggling it out.



Step 5 (optional) - Cover the connection with a piece of tape.



Because the motherboard is on, we don't want the metal parts of the cable to touch the pcb and cause a short. Simply cover the head with a very small piece of tape and you are set!

Put the unit back together and you should be good to go!



Option 2. Disable the camera in Device Manager

If you can see your camera in windows (a.k.a. it's working intermittently) you can disable it in device manager under camera and imaging devices
Because I already hard-disabled mine it will not show up... so I have no picture for you.


In case you were wondering, the reason these cameras are going bad in the 5670 series is due to the "rotation option" built into the web cam. You will notice that you can turn the camera a full 180 degrees around and have it face outwards, this leads to stress on the internal power and transfer cables built into the unit.

All new units have a fixed camera that can not be rotated, this was probably due to this issue... (at least that's my opinion)

I hope this will help other people in their endeavors. If you have any questions let me know.

Thanks
